a a few of these funky looking Mullard OC45 with Blue jacket marked "Mullard OC45 AA"

A couple of them are showing up on my Atlas Peak meter as "PNP silicone", same hfe and leakage range as the others?

Any one know what the deal is?

It's the Peak. Mine does the same thing some times. Must be the way it reads things sometimes. Maybe too little leakage to read as germanium? Who Knows?

The leakage theory sounds Good to me, they all have 0.00ma.

I've had OC71s do the same thing, nothing to worry about.

I have had my atlas do the same here as well, always wondered why but that seems to make sence..

i've actually had a few silicons show up as germanium!!! i think those peaks have a mind of thier own sometimes!

I've seen this as well. I think the Peak DCAs determine that by looking at the Vbe measurement. Not sure what the actual threshold is, but maybe something like Vbe > 0.6V is considered silicon.
